*Questionable calibration number for tank. Old value of 426.62ppm agrees better with round robin (October 2015).
Additional tubing length: 5 m
Notes: Reference Tank CA06343 is currently not in use. (11/2013 moved tank to Site 11).
New pump at time of installation
Firefighter training building is 500 m from the tower
– Uses medical methane as “smoke” for training purposes
– Real fire 1-2 times per year
